Clamps hold workpieces in place by applying consistent pressure via spring, ratchet, lever, or hand screw mechanisms. Angle clamps facilitate right-angle joining and fastening applications. Band clamp tools apply evenly distributed pressure throughout the clamped area. Bar clamp/spreaders have removable end fasteners that can be reversed for spreading items. Bar clamps, pipe clamps, and L clamps can adjust to the length of a large workpiece before applying pressure. Cantilever and T-clamps resist distorting or twisting while being tightened. C-clamps have fixed-width, C-shaped frames, and adjustable hand screws to secure workpieces. Locking clamps have quick-release triggers and adjustment screws for one-handed operation. Spring clamps offer one-handed operation while strut and spring compressors compress and hold automotive strut springs when disassembling struts and replacing shock absorbers. Toggle clamps and hold-down clamps mount to work surfaces and hold workpieces in place.
